Morphology

private + line

The meaning 'a telephone line dedicated to a single user' is directly and transparently derivable from combining 'private' (reserved for specific people) with 'line' (a channel for communication). This compositional noun phrase follows a common, cross-linguistic pattern (e.g., 'private room', 'private office') and would be understandable to a B1 learner who knows both constituents.

Etymology

The noun private line comes from early telephone days when many homes shared one wire and people could hear each other's calls. A private line was a separate wire just for one person or business, so the phrase now means 'a telephone line used only by one person or company'.
